Quartering winds
Quartering winds
(OP)
I heard someone talking about quartering winds, but unfortunately was not able to follow up. It's my understanding that in the case of a rectangular building, a quartering wind is one that is not orthogonal to either of the building axes. When is it appropriate to consider a quartering wind? Is it mostly a consideration if you have lateral resisting elements that that resist lateral loads applied to each orthogonal axis, like a corner column that has rigid connections for each axis?

These load cases are required for all designs >60' and as of ASCE 7-02 for all buildings period - even if they are less than 60'.

I brought up a related topic a few weeks ago in thread507-125928
My interest was that considering orthogonal seismic loads and wind loads per ASCE Figure 6-9 can result in many load combinations, the number of which depends of several factors. There were some interesting comments and I thought it was a good discussion.
These loads are important for columns that resist wind or seismic forces from both directions on a building. I've done a lot of work designing elevated bins where the height to width ratio is relatively large, and the effects quartering wind and orthogonal seismic loads are significant.
